Try running premium or mid-grade gasoline in it. When checking your ignition timing the transmission should be in drive, parking brake set, and the vacuum advance hose disconnected at the distributor and plugged. If you have an EGR valve be sure it's hooked up to the vacuum temperature temperature switch, usually on the thermostat housing, and the vacuum coming to the switch should be carbureted vacuum. Not intake manifold vacuum. Lastly, be sure the centrifugal advance mechanism in the distributor is working correctly. HTH. -Jim

Was the engine built with high compression pistons?

Pre-ignition.. A common battle with the Olds engines. I always ran 93-94 octane fuel with an octane booster to slow the burn. As mentioned above, check the vacuum advance on the distributor and the mechanical mechanism. Verify all vacuum lines are good, no cracks or splits. I would acquire a vacuum diagram to double check routing is correct.

But before doing any of that make sure the ignition wires are on correctly. If a couple of them are reversed, the engine will run, sort of, but under load it starts to stumble and has no power. It's easy to mix them up when putting things back together. Seen it a million times.
